This invention relates generally `to metalworking tools and,emorefparticularly, to a certain new and useful imlprovement in toolsl p especially adapted for ro ingY out dents and 'Jlthe like m automobile fenders, my invention having for its chief 'object the provision of v a tool of the -t pe and for-the purpose stated which is simp e and inexpensive in construction, compact and durable, readily engageand easily operatively manipulated, and e vcientin the performance of its intended functions. And with the above and other objects in e view, my tures of form, construction, arrangement, and combination of partshereinafter described and pointed out in the claims. Y

In the accompanying drawings,- Figurel is a reduced perspective view of I 2 a fender-rolliniool-of my inventiomillustrated as in wor g operationupon a fender Figure 2 is an 'elevational view, partly broken? away and'insection, of the tool; Figure 3 is ,an enlarged detail section of- A 'thetool, taken approximately on the line Figure 4 is a view, somewhat similar tol Figure'l, of atslightly modified tool of my invention. y Referring nowmore in detail and by reference characters to the drawings, which j illustrates practical embodiments of my invention, A designates the frame or body of A the tool, which is constructed of any suitable material, such, forexample, as rigid, lightweight metal, and which has approximatelyl the form or shape of theletter C, the frame or body A of the tool of Figures 1 and 2 com'- prising suitably spaced cross-members 'or arms, 1, 2,'preferably rigidly jointed at one end by a connecting-piece 3. Re-enforcing the upper arm I somewhat arcuate brace 4;. In the tool A of Figures 1 and 2, the lower arm` 2 projects obliquely from the connecting-piece 3 toward the upper arm 1, while in the-tool A of Figure 4, the lower arm 2 has more exactly Athe curvature of the lower portion of the letter-C; otherwise the tools A andfA arev invention'resides in the novel fea- 1,`-is a preferably integrall 'similar in structure, andfhence a' description of one will equally apply to the other.

At its free end, the arm 2 has .an extension 5 presented toward the free end of the arm -R 1 and formedin the extension 5 is a recess 55. 6 approximately `of U-shapel insection, "asl shown, for accommodating a roller 7 dis-` posed -for rotation therein as by means of a supportlng shaft 8 having a bearing in the spaced walls of the recess `6, as best seen in Figure 2; 7' l For purposes shortly appearing, the roller. 7 .has an'arcuate periphery, as at 9, which is preferably of reduced width relatively to the approximately straight periphery 10 of a co- 65.

operating opposed roller 11, which is disposed for rotation in a similar approximately U-shaped recess 12 of a bracket 13 and supported for such rotationas by means of a shaft 14 having a vbearing in the spaced `Walls 70 of the recess l2, also as best seen in Figure 2.

Prpsented outwardly from the lbight of f the bracket 13 and having a recess 15 `in o posed relation to recess 12, is a boss 16.` Fltted for threadedadjustment in the free end of' arm l, is a screw-member 17 having its( head-end 18 presented outwardly of the arm -1 and its opposite' end 19 presented toward the bracket 13, said screw-'end 19 4being nonthreaded and fitting inthe boss 16, as like- 3.0 wise best seen in Figure 2. f At its end 19, the, screw 17 hasf a circumferential slot or groove 20, and seated in the bracket 13 and engaging in `the groove 20, is a set-screw 21 for 'securing the member 17 and bracket .13 together in 35 such manner that, upon ladjustment of the screw-member17, the bracket 13 and `its supported roller 11 will be shifted' toward or from the lower roller 7 to meet Working conditions; "-0 Projecting laterallyl from the bracket 13, is a lug 22 provided with a threaded recess 23 to seat the threaded end' of a short staff 4or bar 24 freely slidable, on adjustments ofthe 95 screw-member 17 in an aperture 25 provided in an extension 26 presented forwardly from the free end of arm l, whereby the Vbracket 13 and its 'carried roller 11 are rmly hel from turning or rotatory movement relatively to.

20 both facile engagement of the tool with the the lower arm 2 both during adjustments and lWorking operations thereo As so constructed, some of the operativel functions of the tool are illustrated in Fig` ures 1 and 4. The upper roller 11 being rst adjustably shifted away from the lower roller 7 the tool is readily mounted operatively upon the fender F, with the arms 1 and `2 embracingly disposed Aupon opposite sides thereof, when the roller 11 is shifted toward the lower roller 7 and the fender F engaged therebetween. The tool is now through and by manual manipulation of the frame A reciprocated longitudinally or lengthwise of the so-engaged fender F, the rollers'7 and 11 at their dilferently shaped and sized periphbody and rim or margin thereof, without eries 9 and 10 co-operating in effecting removal fromthe fender F of dents and the like. I'may add that the peculiar, novel C shape or form of the frameA of thetool enables fender and manual manipulation of the tool lengthwise of the fender throughout both the necessitating removal of the fender from the automobile. 'f

My new tool fully accomplishes the objects yand purposes stated, and it is to be understood that changes in the form, construction, arrangement, and combination of the several lparts of my new tool may be, made and substituted for those herein shown and described `without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A fender rolling tool including, in combination, 'a' rigid frame for manual mani ulation of the tool and comprising spaced ijrst and second arms, a piecejoining said arms at an end thereof, an extension upon the second Jto arm presented towards the first arm, and an* arcuate brace re-enforcingly joined to the first arm, the arms and said'extension being adapted to embrace the fender therebetween arms at an end thereof, an extension upon the second arm presented towards the first arm, i

and an arcuate brace re-enforcingly joined at its ends to the'irst arm, the arms and said extension being adapted to embrace the fender therebetween and said extensionhaving a U-shaped recess in its free end, a screw threaded for adjustment in the free end of the first arm in aliningirelation with said extension, a bracket having a U-shaped recess swiveled intermediate thefirst arm and said extension .upon the lower end of the screw, a bar attached at one end to the bracket and having slidable connection with the first arm for retaining the bracket against rota movement relatively-to the frame both during adjustments of the screw and working operations of the frame, a roller carried by and mounted for rotation in the recess of the bracket, and an opposed roller mounted for rotation in the recess of said extension, said rollers being adapted for engaging the opposite faces of thev embracedI fender.

In testimony whereof, I have signed my name to this specification.
